We
provide a broad range of LCD testers, also
known as a digital video generator or flat
panel display tester,
for display modules and display panels
ranging from small format cell phone
displays to large TFT panels for LCD TV. Our
testers give you control over video timing,
power levels, image content, and in most
cases, inverter controls for backlighting.
T-Drive™
Profile:
A T-Drive™ profile is an electronic
definition of how to drive a display
module. Included in the profile are: timing
/ electrical definitions, voltage settings
for power rails, power sequence definitions
for power up and power down, descriptions of
ancillary interfaces, such as an inverter,
discrete I/O or a SPI interface. The Profile is assigned a name and a number and can be
quickly selected and applied from the handheld
keypad. This unique approach allows
profiles to be controlled by test engineers
and used by test technicians.
Our T-Drive™ family of products feature
PC-based software to allow the test engineer
to set up all the required profiles (see
side bar) and images within a unit. The test
technician can then perform easy-to-learn
operations from a handheld keypad, making
the T-Drive™ a truly easy-to-use tester for
multiple display part numbers!
T-Drive™ products provide fast, flexible
image changes. The user has two choices for
image content: built-in images or downloaded
bitmap files (see side bar), providing the
ultimate flexibility for required test
images.

Our
T-Drive™
Model
I
is a TFT tester, (or TFT
driver) ideal for the TFT repair industries
and for automated measurement systems.
This TFT driver has been a market leader
for over three years!
-
Our
T-Drive™
Model
II
is a TFT similar to a Model
I,
but
with enhanced power and a 10 bit LVDS
output
-
Our
T-Drive™ SD100 is
the industry's
first universal tester to drive most
small format displays on the market
today, from RGB interfaces to CPU
interfaces to SPI serial interfaces! The
unit includes accurate LED drive. The
SD100 is used primarily as a cell
display drive unit.
-
Our
T-Soak™ provides (4) identical
outputs simultaneously. This is ideal
for burn-in testing as well as
comparative analysis of panels.
Built-in images and Bitmap images:
T-Drive™ includes built-in images
that are common for test purposes.
These images are created based on
the resolution of the currently
selected image. Thus, built-in
images support all possible
resolutions. In most cases, the
intensity of the image is selectable
via the keypad, providing nearly
infinite amount of image
selections! For example,
T-Drive™ Model
I
supports 8 bits per
color. Therefore, any full screen
color is selectable from the keypad,
providing 16 millions colors!
These images are created real-time
inside T-Drive™, and require no
internal storage. For complex test
patterns, the user can download test
pattern bitmap files into the
non-volatile storage within the
T-Drive™, providing dozens of
additional test patterns!
Other Universal Tester products and services
include:
-
Tooling Solutions to support the test of
your display on our products. Tooling
usually includes a file to configure the
tester, as well as an interconnect
solution.
